  • Self-adhering tape seal made from resilient, open-cell polyurethane foam impregnated with water-based acrylic-modified asphalt emulsion and then compressed to a sealing density level appropriate to the application
  • Used to seal out dust, air, wind-driven snow & moisture through joint details in metal building & roofs
  • Ideal as a filler in expansion & compression joints subject to movement from thermal expansion & contraction
  • Use against metal, plastic, wood, concrete & other building materials common in metal building construction
  • Will not dry out and become hard and brittle
  • UV-stable
  • Highly resistant to bugs and vermin
  • Will not extrude from between joints like caulk or butyl tapes
  • Conforms to contours and fills gaps
  • Maintains a seal during thermal expansion and contraction of building panels
  • Excellent compressibility and recovery (minimal compression set)
  • Good thermal and sound insulator
  • No shrinkage or blow-out due to closed-cell breakage
  • Supplied with self-adhesive on one side. After removal of packaging, material begins gradual expansion - more slowly in cold weather than in hot
